Is that moveable instrument with a flie, whereon are described the 32 points or winds by which we direct the steere, our courses at sea. The fashion is knowne to all, and for the uses, they are handled at large in many books which write of Navigation. There are three kinds; First the plaine Meridionall compasse (which is the or∣dinary one;) the second, a compasse of Variation, which shewes the
variation of the Compasse from the true north and south. The third, is a dark-compasse, which being but an ordinary compasse in use, is only so called, because the flie hath the points described with no colours (as the other are, but only black and white, being most convenient to be seen, when we steere by night, without any light, but only skie-light.
